Title: FRICTION DISC FOR A CLUTCH DISC DAMPER
Abstract:
A friction disc (24) is provided for frictional damping in a clutch disc damper (10), said friction disc having: a friction ring (34) for bearing frictionally against an input flange (14) or output flange (22) of the clutch disc damper (10); a fastening region (36) for rotationally fixed fastening to the output flange (22) or input flange (14) of the clutch disc damper (10), which flange can rotate relative to the friction ring (34); and at least one spring element (38, 44), which is coupled to the friction ring (34) and to the fastening region (36), for providing resilience in the radial direction, wherein the friction ring (34) is movable in all radial directions relative to the fastening region (36) as a result of the at least one spring element (38, 44). Thanks to the radial resilience of the friction ring (34) of the friction disc (24) which is achieved with the aid of the spring element (38, 44), high-frequency noise can be avoided during coupling of a clutch disc, permitting a motor vehicle drive train with a low noise level.
